CLAIR C. HARPER, OF ROCHESTER, AND EUGENE IE. KITENDAUGH, OF ONEIDA, NEW YORK, ASSIGNOR-S TO ERROR-NO 1110., OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK COPYHOLDEB Application filed September 17, 1929. Serial No.'393,304.

Our invention relates to copy holders and especially to that type of copy holder adapted to hold and feed a very wide or long record side of the machine and to permit it to ex tend to the rear of the machine to prevent crumpling of the sheet. Another object of our invention is to provide a support for the rear end of the sheet in the copy holder which also serves as a support for the copy holder frame. Another object of our invention is to provide a copy holder with feeding means adapted to positively engage the copy sheet so that all parts of the wide sheet are fedat a uniform speed. Still another object of our invention is to provide adjustable reinforcing means for the feeding devices in a copy holder to maintain a uniform pressure on the sheet throughout its width.

sists of certain parts and combinations of parts, all of which will be hereinafter described: the novel features being pointed out in the appended claims.

Fig. 5 is a similar view on the line 5-5, Fig. 3;

Fig. 6 is an enlarged sectional view of parts shownin Fig. 2; and V Fig. 7 is a side view partially in section of another embodiment of my invention.

The present embodiment of our invention comprises a frame having upwardly and rearwardly extending members 1 to whichforwardly and upwardly extending braces 2 are To these and other ends, the invention 0011- secured. Secured to and extending between the upright members 1 adjacent their upper ends is a housing or supporting member 3 provided with forwardly extending portions 4 and 4 in which the paper clamping and feeding devices are mounted. Mounted on a rod or bar 5 and extending between the supporting members 1 near the base of the device is a sheet holding and supporting member'6 extending downwardly and rearwardly therefrom and at its lower rear end extends to a point in the plane on the bottom of the frame. At its rear end the support 6 has formed thereon a flange 7 to retain sheets in the sup port. t its forward end, the support 6 is curved upwardly and forwardly at 8 for supporting and directing the sheets as they are drawn from the support 6.

Arranged on the front of or integral with the member 3 is a sheet supporting plate or table 9 arranged above the support 6 and on which the sheets or copies are supported as they move to the feeding devices. Movable in said support behind the plate 9 is a shaft 10 on which are mounted a plurality of clamping members or rollers 11 in position to project through openings provided therefor in the plate or table 9. Rev olvably mounted in the support, 4 in front of the table 9 is a shaft 12 on which are mounted'a plurality of feed rollers 13 adapted to engage the rollers 11 or a sheet placed thereon. The shaft 10 is mounted for movement to carry the rollers 11 to and from engagement with the feed rollers 13 and is resiliently held in such engaging position by means of springs 1% which engage the shaft 10. Means are provided for moving the shaft manually to move the rollers 10 out of engagement with the rollers 13 against tension of the springs 14;. Said means comprises a shaft 15 journalled in the supporting member and extend ingparallel with the shaft 10. Adjacent the ends of the shaft 10 the shaft 15 is provided with arms 16 projecting therefrom and adapted to engage the shaft 10. A finger piece 17 is secured on the shaft 15 for rotating the same to move the rollers 11 out of engagement with the rollers 13.

The shaft 12 is on which the rollers 13 are mounted is angular in cross section as shown, and engages corresponding openings in the rollers 13 to prevent the rollers from slipping on the shaft. We have provided means for positively engaging the sheet so that both sides of a wide sheet will be fed forwardly at the same speed and creeping of the sheet prevented. To this end, the rollers 11 and 13 are provided with gripping means preferablycorrugations, as shown, and the sheet is gripped between" the opposing corrugations on the rollers.

When feeding very wide sheets, it some times happens that the feeding shaft has a tendency to spring from the work causing uneven pressure to be exerted on the sheet resulting? on a feeding of diflerentportions of the sheet at different speeds. To overcome this, we have provided means for reinforcing the angular shaft 12 at one or more points intermediate its ends. To this end, a supporting member 18 extends across the support 3 over the angular shaft 12 and has threaded therein a screw 19 having an abutment 20 swivel-ed at its inner endand adapted to engage a cylindrical portion- 21 on the shaft 12-. The outer end of the screw 19 mayv be provided with a finger piece 22 for adj usting the same.

Means are provided for imparting a step the end of the shaft 12 and engages a wheel 24 revolvably supported on one of the supporting members 4 which in turn meshes with a wheel 23 mounted on a shaft 26 which is rc'volvab'ly supported in the. member 4, and a member 27 on the support 3. At its outer end the'sha-ft 26 is provided with a finger piece bywhich it may be manually rotated in either direction. To impart stepby-step feeding movements to the rollers 13 a friction wheel 28 is mounted on the shaft 26 and a dog or pawl 29 is pivoted on a manually operated lever 30 for limited movement thereon. The lever 30 is mounted to swing on the shaft 26 and has an inwardly extending finger 31 which engages the dog and moves it into clamping er'rgagement with the wheel 28 which thereafter moves with the lever. A spring 32 resiliently maintains the lever in normal retracted position and a pair of stops limits its movement in either direction.

Mounted on the support 18 and curving downwardly and forwardly to a point adja-' cent the table 9, is a housing' member 33 which conceals the intake side of the feeding devices and cooperates with a line guide 34- adjustably mounted on the table 9' and providing a line of vision therebetween. A second hous ing member 35 for the feeding devices is also mounted on the support 18 and extends up wardly and rearwardly therefrom past the table 9 and serves to deflect a sheet moving from the table rearwardly into a tray or pocket 36 provided therefor on the rear of the frame. Said pocket is secured to the member 3 and supported on brackets 37 extending upwardly and rearwardly from the frame members 1. The pocket or tray 36 extends downwardly and rearwardly from a" point adjacent the discharge side of the machine and is adapted to receive and shut when discharged. At its rearend a flange 38 is provided which serves as a stop for the sheets. It will be noted that the sheet supporting devices 6 and 36 are arranged one above the other on the rear side of the frame with the feeding devices between them and provide means for supporting. the opposite ends of a long record or work sheet. 7

In the embodiment shown in Fig. 7 the sheet feeding means is the same as that shown in the other embodiment. The sheet as it passes from the feeding means travels over a guide 39, the lower portion of which is aligned with the feeding mechanism.- From the feeding mechanism,- the guide proceeds upwardly, rearwardly and then downwardly in a vertical plane in rear of the supporting members 1.

The sheets pass from the guide to the re-' ceiver or tray 40 which is arranged in a rear wardl-y inclined position in rear of the supporting member 1, its lower forward portion resting on brackets 41 which are carried by the braces 2. Braces 42 connect the sides of the receptacle with the forwardly projecting. portions 4; and 4* in which the feeding mechanism is arranged.

The sheets in dropping from the guide 39 proceed with their upper edges first toward the lowermost part of the receiving tray. In

this way the front face of the sheet on the V feeding mechanism becomes the rear face of the sheet in the tray. In other words, the position of the sheet is reversed. This is important when a stack of sheets are being successively used in the copy holder and it-is desired to maintain the order of the sheets in a stack after passing through the copyholder.

It will be noted that we have provided a simple and inexpensive copy hold-er designed to conveniently handle large copy sheets. We have provided improved means for positive- 1y engaging the sheet to compel all parts to move at thesam-e speed to prevent creeping.
